Be VERY careful should you do something like that!!!!!! There's a couple of soda cans in there that could give you a shocking experience should you put your fingers on the wrong places. Always connect a light bulb to the different connectors in order to remove any power left in the capacitors.

You do not need to disassemble the PSU, you can connect the power terminals directly to the wires outside the PSU chassis. Won't be as neat looking though.
